If one or more interior grease interceptors are provided, which wastes may bypass the interceptor or interceptors?

If one or more interior grease interceptors are provided, which wastes may bypass the interceptor or interceptors?

• A. Wastes from a food waste grinder
• B. Sanitizing compartment of a sink
• C. Rinse compartment of a sink
• D. Wastes from a food waste grinder, sanitizing compartment, or rinse compartment

Answer: (D)

Grease interceptors are meant to trap fats, oils, and grease from kitchen wastewater, but not every waste stream should go through them. Some discharges can hinder the interceptor’s function or cause problems if they pass through it, so they are routed to bypass. Wastes from a food waste grinder produce a lot of solids and ground-up food that can clog or overwhelm the interceptor and aren’t the type of waste the interceptor is designed to handle. The sanitizing compartment and the rinse compartment discharge water often contains detergents or sanitizers and may be hot; these conditions can emulsify fats or alter the wastewater in a way that reduces the interceptor’s effectiveness. By bypassing these streams, the interceptor remains able to do its job with the rest of the kitchen effluent. So, wastes from a food waste grinder, the sanitizing compartment, or the rinse compartment may bypass the interceptor.
